This Yongnuo YN24EX Twin Flash Diffuser is a clip on double diffuser design. It allows for the use of different diffusion materials which can be separated to allow for different effects and generally better diffusion for the given length of the diffuser bodies.

I have done testing with different materials and have found the use of 2x layers of baking paper at the first joint and paper towel at the end gives the best diffusion but this can be changed to whatever is desired.

When installing or removing the diffusers, make sure to do so from one side at a time and do not push or pull square to the flash bodies as this will break off the clips. I have installed and removed these dozens of times with no damage to the clips using this correct method.

This design uses 16x Ø9.5 x 1.5mm Magnets from Everhang ( https://www.ehi.com.au/everhang-9.5x1.5-super-strong-self-adhesive-magnet )

I have included the .STEP files of the models so that magnet sizes can be changed and I am happy to upload designs for different magnet sizes if requested.
